Title: A process for the production of thermostable acrylonitrile polymers
IPC: C08F220/06
Filed: 1959-08-28
Abstract: Copolymers are prepared by copolymerizing acrylonitrile with an unsaturated carboxylic acid in which the carboxyl group is separated from the nearer atom of the carbon-carbon double bond by a chain of at least four atoms, at least one of which is a nitrogen atom the remainder being carbon atoms, e.g. the acid amides prepared by the reaction of acrylic, methacrylic and crotonic acids, or chlorides thereof, with amino-acids, and the reaction products of unsaturated isocyanates, such as beta-isocyanatoethyl methacrylate, with amino or hydroxy carboxylic acids.  Acids specifically described are acrylo- and methacryloepsilonamino caproyl-epsilon-amino caproic acids, and epsilon-aminocaproyl-glycines, methacrylo-glycylglycine, methacrylo-glycylalanylglycine, acrylo-aminocaproylglycylglycine and methacryloepsilon-aminocaproic acid.  Other monomers may be present during polymerization, e.g. methyl acrylate, methacrylic esters, styrene, vinyl chloride and vinylidene chloride. Polymerization may be carried out in bulk, solution or emulsion with the aid of catalysts such as hydrogen peroxide, persulphates, azodiisobutyronitrile and mixtures of persulphates and oxidizible sulphur compounds, e.g. sodium pyrosulphite.  The polymerization is preferably effected in an aqueous medium at pH values below 7. The copolymers produced preferably contain a high proportion of acrylonitrile, e.g. at least 90%, so that they may be processed into films and fibres.  Such films and fibres have good dyeing capacity and thermostability.  In a comparative experiment the preparation of a copolymer of acrylonitrile, methyl acrylate and methacrylo-aminoacetic acid is described.  Specification 867,528 is referred to.ALSO:Ethylenically unsaturated acid amides are made by reacting acrylic, methacrylic and crotonic acids or halides with amino acids or peptides, e.g. beta-aminopripionic, gamma-aminobutyric, epsilon-aminocaproic, epsilon-aminocaproyl - epsilon-aminocaproic and p-aminobenzoic acids, epsilon - aminocaproylglycine, glycylglycine, glycylalanylglycine and aminocaproylglycylglycine.

Abstract: 261,803. Svenska Aktiebolaget Mono. Nov. 23, 1925, [Convention date]. Addition to 217,242. Recording by distinctive marks.- Relates to improvements in the indicating and recording device of a gasanalyzing apparatus as described in the parent Specification. According to the invention the ratchet wheel actuated by the electromagnetic impulses sent out by the movement of a submerged bell receiving the residual gases is replaced by a rack operating a recording pen arm. The pen arm may be mounted directly on the rack so that at the end of the test when the rack is released the pen moves back to the zero position or it may be carried by members controlled by the rack so as to move from one maximum position at the end of a test to that for the succeeding test. In the form shown in Fig. 1, the excitation of the electromagnet i by the impulses due to the movement of the submerged bell causes the armature k to be attracted and through the pawl x<1> displaces a rack m against the action of a spring z, the rack being held in its set position by a detent x. After each test the electromagnet r is energized and through its armature q and links p effects the withdrawal of the pawls x, x' to release the rack m and recording pen g. In a modification, Fig. 2, two recording pens g', g<2> are provided mounted on bars b', b<2> operatively connected through a forked member a with the rack m. The bars b', b<2> are provided with fixed collars y<1> - -y' between which and bushes c<1> - - c<4> are arranged springs d<1> - - d<4> the bushes being loosely mounted on the bars on either side of the member a and pressed against sleeves o<1>, o<2> on the bars and situated within the forked end nf the member a. Brakes u<1>, u<2> normally hold the bars b<1>, b<2> in position. In operation when the rack m is shifted the member a compresses the springs d<3>, d<4> and at the end of a test one of the brakes u<1> or u<2> is released to permit the corresponding bar to move to recording position. The brake is then applied and the rack m moves back to normal position for a second test at the end of which the bar which has been shifted moves to its new indicating position. Two recording arms are provided and operated alternately when it is desired to ascertain the CO and CO2 content of the gas mixture. The bars b<1>, b<2> may operate indicating pointers A', A<2> co-operating with scales.

[Also in Divisions H2 and H3] Apparatus for determining the position of a mark includes an optical scanning device oscillating the field of view of a photo-electric detector about a mean position and provision for using the detector output to cause the mean position to coincide with any mark in the field of view. The optical scanning device may take the form shown in Fig. 1 where two facing annular permanent magnets having central apertures carry resilient membranes 18, 19 at their outer ends to which are attached the ends of a support 20 carrying a tubular former 22 with extremities positioned in the two gaps. Windings 23 and 24 on the former lie in the respective gaps and the former carries a slotted mask 26 by means of an arm 25. Fig. 2 shows the winding 23 and 24 and the mask 26 and indicate how the winding 23 feeds amplifier 34 through capacitor 31 and transformer 33. The output of the amplifier is fed through transformer 32 and capacitor 30 to winding 24 to cause the former 22 to oscillate up and down carrying the mask with it. A collimated light beam is directed through scale 37, the position of one of the marks on which is to be investigated, to the mask 26 and light passing through the slot falls on photo-electric detector 38. The amplified and limited output from the detector is applied to phase-sensitive rectifier 42, which also has an input dependant on the current causing oscillation of the mask 26, to give a substantially d.c. output from smoothing stage 43 which is applied to coils 22, 23 is series to bias the position of the mean position of the mask. The current form stage 43 is indicated at 44 and with adequate amplification meter 44 will show the position of the mask to an accuracy of 1%. The meter may be replaced by a recording device. In another embodiment (Fig. 3 not shown) the oscillating scan is obtained by oscillatory angular movement of a thick parallel-sided glass block about an axis perpendicular to the optical axis of the system and parallel to the block faces. In their mean position the block faces are perpendicular to the optical axis. In this arrangement the output of stage 43 is fed to adjust a separate refractive element in the optical path to bring the mean position of the detector field of view into coincidence with the mark.
